Galaxies are large systems of stars, gas, dust and dark matter that orbits a center and is bound by gravity. Learn about the characteristics of galaxies.
Choosing a transfer orbit The basic principle is this: As orbits get bigger, their periods increase. Higher is slower - orbit radius is inversely proportional to orbital velocity. So if you are "ahead" of your target and want it to catch up, you should go into a higher orbit (one with...
(like a circular orbit). if it is moving with a constant speed in a circle, the magnitude of the change in vector momentum would be: r is the radius of the circle. if you like to look at this in terms of the speed of the object, v is the magnitude of the velocity. or maybe ...

If you know that a particle is moving in a circular path with a velocity v at a distance r from the center of the circle, with the direction of v always being perpendicular to the radius of the circle, then the average angular velocity can be written as: ...

I'm sorry to say that's another arithmetic error. Mar 25, 2019 #41 Davidllerenav 424 14 haruspex said: I'm sorry to say that's another arithmetic error. I see, I made a mistake when I squared 0.02, it is 0.0004, not 0.004. so ##E_k=\frac{1}{2}m(0.0004)v_...
As Cancri 55 e transits in front of the star, the EXPRES instrument at the Lowell Observatory measures the star’s light precisely. Those measurements reveal apparent,but not real, deviations in the planet’s radial velocity, and those deviations tell astronomers about the planet’s orb...
You can reduce this force considerably by touching down at a lower velocity. It also helps a lot if you can find a level place to land, though this isn't always practical. === Rotors === The basic goal of a rotor is to apply some torque to rotate some small portion of the ship...
Simulations of clusters with orbits like Gaia 1 find that they are stripped of stars and dispersed by these high velocity 'plane passages'. That puts it at odds with the age estimate. "Our finding that Gaia 1 is three billion years old is curious as the models would have it not surviving...
